I have two models namely MedicineRequestEntry and MedicineRequest. MedicineRequestEntry is related to MedicineRequest via
public function getMedicineRequests()
{
return $this->hasMany(MedicineRequest::className(),
['medicine_request_entry_id' => 'id']);
}
Now in grid-view of MedicineReuestEntry I am trying to pull the data from MedicineRequest Model using the relation using two alternative ways
like
[
'attribute' => 'is_delivered',
'value'=> 'medicineRequests.is_delivered'
],
In this method I am getting the value as not set.
and another method:
[
'attribute' => 'is_delivered',
'value'=> '$data->medicineRequests->is_delivered'
],
In this method I am getting the error like:
Getting unknown property: app\models\MedicineRequestEntry::$data->medicineRequests->is_delivered
Now I need some help, what I am doing wrong here.
Thank you.
You should use a callback function, see the guide:
[
'value' => function ($data) {
$str = '';
foreach($data->medicineRequests as $request) {
$str .= $request->is_delivered.',';
}
return $str;
},
],
Or for the first result of the array:
[
'value' => function ($data) {
return $data->medicineRequests[0]->is_delivered;
},
],

I am creating a custom Identity interface without created_at property. I got an error :
"name": "Unknown Property",
"message": "Setting unknown property: api\\common\\models\\User::created_at",
I tried to comment the TimestampBehavior, but I got the following error:
"name": "PHP Warning",
"message": "Invalid argument supplied for foreach()",
I want to know where is the problem.
Model class:
class User extends ActiveRecord implements IdentityInterface
{
public static function tableName()
{
return '{{%user}}';
}
public function behaviors()
{
// return [
// TimestampBehavior::className(),
// ];
}
/**
* #inheritdoc
*/
public function rules()
{
return [
[['purpose'], 'required'],
[['status'], 'integer'],
];
}
}
for the rest controller the action is
public function actionLogin(){
.
.
.
$api_user = new User();
$api_user->purpose="app";
$api_user->status=User::STATUS_ACTIVE;
if($api_user->save()){
$success = true;
}
}
This will automatically resolve the issue. BlameableBehavior and TimestampBehavior
// Include these on the start
use yii\behaviors\BlameableBehavior;
use yii\behaviors\TimestampBehavior;
use Carbon\Carbon;
// Paste this function inside the class.
/**
* #return array
*/
public function behaviors()
{
return [
'blameable' => [
'class' => BlameableBehavior::className(),
'createdByAttribute' => 'created_by',
'updatedByAttribute' => 'updated_by',
],
'timestamp' => [
'class' => TimestampBehavior::className(),
'createdAtAttribute' => 'created_at',
'updatedAtAttribute' => 'updated_at',
'value' => Carbon::now(),
],
];
}
NOTE: If you are not using updated_at or updated_by then remove it
form the above code
change your Behavior in your model to:
public function behaviors()
{
return [
'timestamp' => [
'class' => 'yii\behaviors\TimestampBehavior',
'attributes' => [
ActiveRecord::EVENT_BEFORE_INSERT => ['updated_at'],
ActiveRecord::EVENT_BEFORE_UPDATE => ['updated_at'],
],
'value' => new Expression('NOW()'),
],
];
}
if you haven't updated_at also delete it from attributes.
You were getting following warning because you've completely removed the return in the behaviors() method.
"name": "PHP Warning",
"message": "Invalid argument supplied for foreach()",
The behaviors method must return an array. If you don't want to use any behavior your behaviors() method should return empty array like this:
public function behaviors()
{
return [];
}
This is also default implementation of behaviors() method in yii\base\Component so if you don't need to use any behavior you can simply remove the behaviors() method from your model.
Attaching TimestampBehavior to your model when you are not using it means that you add unnecessary overhead.
Example: Rename and prevent time recording or remove properties. Also change the value
Rename or delete properties or change value.
public function behaviors()
{
return [
[
'class' => \yii\behaviors\TimestampBehavior::className(),
'createdAtAttribute' => 'created_at',
// 'createdAtAttribute' => 'c_time', //Change the name of the field
'updatedAtAttribute' => false, //false if you do not want to record the creation time.
// 'value' => new Expression('NOW()'), // Change the value
],
];
}
Or
'class' => \yii\behaviors\TimestampBehavior::className(),
'attributes' => [
\yii\db\ActiveRecord::EVENT_BEFORE_INSERT => ['created_at'],
// \yii\db\ActiveRecord::EVENT_BEFORE_UPDATE => [],
],
$createdAtAttribute: The attribute that will receive timestamp value Set this property to false if you do not want to record the creation time.
$attributes: List of attributes that are to be automatically filled with the value specified via $value. The array keys are the ActiveRecord events upon which the attributes are to be updated, and the array values are the corresponding attribute(s) to be updated. You can use a string to represent a single attribute, or an array to represent a list of attributes. For example,
[
ActiveRecord::EVENT_BEFORE_INSERT => ['attribute1', 'attribute2'],
ActiveRecord::EVENT_BEFORE_UPDATE => 'attribute2',
]
I need your help!
I'm having problems returning pivot table information when using ApiResources.
If I have a model like this:
Post.php
public function likes()
{
return $this->belongsToMany(Like::class)
->withPivot(['points']) // I want this in my PostResource::collection !
}
When defining its Resources:
LikeResource.php
public function toArray($request)
{
return [
'like_field' => $this->like_field
];
}
PostResource.php
public function toArray($request)
{
return [
'title' => $this->title,
'likes' => LikeResource::collection($this->whenLoaded('likes'))
];
}
Then in PostController.php
return PostResource::collection(Post::with('likes')->get())
It will return something like this:
Controller Response
[
{
'title' => 'Post 1'
'likes' => [
{
'like_field' => 'Test'
},
{
'like_field' => 'Test 2'
}
]
},
{
'title' => 'Post 2',
...
}
]
The problem is, using that LikeResource::collection() it does not appends pivot information. How could I add 'points' of the pivot table when defining that PostResource??
Thats all,
Thx!
Solution
Well, simply reading a bit in Laravel Docs, to return pivot information you just has to use the method $this->whenPivotLoaded()
So, the PostResource becomes:
public function toArray($request)
{
return [
'title' => $this->title,
'likes' => LikeResource::collection($this->whenLoaded('likes')),
'like_post' => $this->whenPivotLoaded('like_post', function() {
return $this->pivot->like_field;
})
];
}
I am trying to access a variable on view file into Gridview but it is throwing error that it should be array but null given i am declaring $totalDays on top of my view file and i am using it in Gridview like below
[
'attribute' => 'class_id',
'format' => 'raw',
'label' => "Class Date",
'value' => function ($model) {
array_push($totalDays,$model->class->date);
return $model->class->date;
},
'footer'=> '<span>Total Days</span>',
],
But it throws following error
array_push() expects parameter 1 to be array, null given
To explain, $totalDays is not available in the widget because the whole function only gets run when the widget is rendered, $totalDays is no longer declared. As #arogachev hinted above, you will need to make $totalDays in your model, then you can access it. Try this in your model;
public function getTotalDays(){
//Your logic here to generate totalDays
return $totalDays;
}
Then you can use it in your view like this;
[
'attribute' => 'class_id',
'format' => 'raw',
'label' => "Class Date",
'value' => function ($model) {
array_push($model->totalDays, totalDays,$model->class->date);
return $model->class->date;
},
'footer'=> '<span>Total Days</span>',
],
Insert use after function signature in value callable function:
[
'attribute' => 'class_id',
'format' => 'raw',
'label' => "Class Date",
'value' => function ($model) use($totaleDays) {
array_push($totalDays,$model->class->date);
return $model->class->date;
},
'footer'=> '<span>Total Days</span>',
],
As #Fabrizio said. Insert use after function signature in value callable function:
'value' => function ($model) use($totaleDays) {
array_push($totalDays,$model->class->date);
return $model->class->date;
},
For multiple value to pass in to value function you can use as below.
'value' => function ($model) use($var1, $var2....., $varN) {
array_push($totalDays,$model->class->date);
return $model->class->date;
},
Like this use($var1, $var2....., $varN)
While you can definetely pass this variable through use section of closure, it's wrong in your code. MVC principle is violated, because view it's only for display, and you exposing logic such as array_push.
I'd recommend to refactor it and place data calculation in model, so you can simply call return $model->yourMethod(); and it will return desired data.
I am beginner. I explain the topic:
there is this relationship in the Ticket model:
public function getTyp()
{
return $this->hasOne(Typology::className(), [ 'id' =>'typ_id']);
}
and in the ticket table there is the typ_id column (it is in relationship with the id of the Typology table).
In the view views/ticket/index.php there is GridView::widgetwith these columns:
[
'attribute' => 'typ_id',
'value' => 'typ.typology'
],
I want to anchor the value of the relationship.
I have tried this:
[
'attribute' => 'typ_id',
'value' => function ($model) {
return Html::a (
'typ.typology',
'/typology/view?id='.$model->typ_id
);
}
]
but it doesn't work
someone can help me?
Html::a() interprets typ.typology as raw string. Use $model in value closure to get necessary property through relation.
Also instead of manually concatenate the url with its parameters, just pass them in array (see Url::to() to understand how link is constructed).
[
'attribute' => 'typ_id',
'value' => function ($model) {
return Html::a($model->typ->typology, ['/typology/view', 'id' => $model->typ_id]);
},
],
I'm building an API in Laravel to learn how to do such a thing. I'm following a Laracasts course to do this, but I'm having some troubles with the parts I want to do for myself.
Currently, I have this function in my controller. It fetches data from two tables and then returns it.
public function lesson($userid)
{
$lessons = DB::table('lessons')
->join('userlessons', 'lessons.id', '=', 'userlessons.lessonsid')
->select('lessons.name', 'lessons.seen')
->where('userlessons.userid','=', $userid)
->get();
return $this->respondWithPagination($lessons, [
'data' => $this->LessonTransformer->transformCollection($lessons)
]);
}
And LessonTransformer is this:
class LessonTransformer extends Transformer
{
public function transformCollection($items)
{
return array_map([$this, 'transform'], $items);
}
public function transform($item)
{
return [
'name' => $item['name'],
'seen' => (bool) $item['seen']
];
}
}
I tried a lot of solutions, some smart, some stupid. But I keep getting this error: Cannot use object of type stdClass as array
If you get such error, probably you need to change:
return [
'name' => $item['name'],
'seen' => (bool) $item['seen']
];
into:
return [
'name' => $item->name,
'seen' => (bool) $item->seen
];
but you haven't showed in which line error appear so it's only a guess
